Go for LELO MIA, or We-Vibe Tango- I love both. Or even OhmiBod Kandi Kisses, though I haven't tried it yet. If you're looking for something cheaper, but still strong, try Screaming O Studio Collection Lipstick Vibe.
I loved mine. It was fantastically fun, especially for a tease to get me going at the stoplights on the way home to my man. Then the dog got a hold of it...and once the little girl i babysat grabber it to. If you decide it's right for you, I'd suggest the Shaki Toys one, it's cheap and based on the reviews about equally as powerful. I also like the bullet that is hidden in the compact. Very discrete.
